Antenna module and vehicle roof with antenna module

Abstract

An antenna module includes: a substrate; at least one first communication antenna by a frequency band belonging to a first frequency range; and at least one second communication antenna by a frequency band belonging to a second frequency range higher than the first frequency range, wherein the at least one first communication antenna and the at least one second communication antenna are provided on the substrate, and the at least one first communication antenna is provided in a position closer to an edge of the substrate than the at least one second communication antenna.

The invention claimed is: 
     
       1. An antenna module, comprising:
 a substrate; 
 at least one first communication antenna by a frequency band belonging to a first frequency range; and 
 at least one second communication antenna by a frequency band belonging to a second frequency range higher than the first frequency range, wherein 
 three or more types of antennas by frequency bands different from each other including the at least one first communication antenna and the at least one second communication antenna are provided on the substrate, 
 the at least one first communication antenna is provided in a position closer to an edge of the substrate than the at least one second communication antenna, and 
 the second communication antenna by a highest frequency band in the three or more types of antennas in the at least one second communication antenna is provided in a position with a farthest distance from an edge of the substrate. 
 
     
     
       2. The antenna module according to  claim 1 , wherein
 the first frequency range is a frequency band equal to or smaller than 2.1 GHz, and 
 the second frequency range is a frequency band equal to or larger than 5.7 GHz. 
 
     
     
       3. The antenna module according to  claim 1 , wherein
 an enclosure which is an obstacle to radio wave is disposed around the substrate. 
 
     
     
       4. The antenna module according to  claim 1 , wherein
 a first communication antenna by a lowest frequency band in the at least one first communication antenna is provided in a position with a smallest distance from the edge of the substrate in the at least one first communication antenna and the at least one second communication antenna. 
 
     
     
       5. A vehicle roof with an antenna module, comprising:
 the antenna module according to  claim 1 ; and 
 a vehicle roof which is an obstacle to radio wave of at least a part of frequency band, wherein 
 an opening is formed in the vehicle roof, and 
 the antenna module is fitted into the opening. 
 
     
     
       6. The antenna module according to  claim 1 , wherein the three or more types of antennas by frequency bands different from each other including the at least one first communication antenna and the at least one second communication antenna are provided on the substrate except for a case where another loop antenna is formed on an inner side of a loop antenna and a patch antenna is formed on an inner side of the another loop antenna.
